Killings was born in Williamsburg, South Carolina, but raised in Charlotte, North Carolina. To make extra money in his early 20's, Killings would sell cocaine on the streets for extra income. From a young age, Killings had developed a love for hip hop and breakdancing and attended Harding University High School where he competed in football alongside future MLB second baseman Ray Durham. Killings also competed in track and field, and was talented at both sports, receiving various college scholarships, but turned them down to further pursue a career in music. Killings graduated High School at 18, but Killings also continued dealing drugs in order to help his music career financially and was arrested four different times, spending small amounts of time before finally being charged heavily spending 13 months incarcerated. Killings spoke in an interview with Lilian Garcia that after this incident Killings was finished with that lifestyle.[9]

Jackie Crockett of the National Wrestling Alliance met Killings at a halfway house after Killings' release from prison, and tried to convince Killings to become a professional wrestler, but he was determined to focus on his music career.[9] Killings spent two years working on his music career and then contacted Crockett once more and expressed an interest in becoming a wrestler.[7] Crockett, by now the senior cameraman for World Championship Wrestling, took Killings to several WCW and Pro Wrestling Federation events, introducing him to wrestling personalities.[8]

Killings debuted in the Pro Wrestling Federation (PWF) in 1997 as a manager, then spent three years traveling and training with Manny Fernandez.[8] In 1999, he debuted in NWA Wildside as K-Krush, where he was awarded the newly created NWA Wildside Television Championship on December 12.

Killings was then promoted to the main roster and put in a tag team with Road Dogg.[8] He debuted on the November 13, 2000 episode of Raw is War, attacking William Regal during a match against Road Dogg. Killings and the Road Dogg began rapping together, performing a song called "Gettin' Rowdy" as they approached the ring.[7] Upon the return of Road Dogg's former partner Billy Gunn later that month, Killings was involved in a D-Generation X quasi-reunion. At Survivor Series, Killings teamed with former DX members Road Dogg, Billy Gunn, and Chyna to face The Radicalz in a Survivor Series match.[8] Killings was eliminated and the Radicalz went on to win the match. At Armageddon, Killings and the Road Dogg took part in a four-way tag team match for the Tag Team Championship, which was won by Edge and Christian.[8] After Road Dogg was suspended in December and eventually released on January 26, 2001,[10] Killings became a singles competitor and became a successful mainstay on Jakked. He took part in the 2001 Royal Rumble, but was eliminated by Big Show. Killings then began competing in the hardcore division. He defeated Raven for the Hardcore Championship on February 3, but lost the title to Crash Holly that same evening under the title's 24/7 rules.[11] He defeated Raven for the title a second time on the following night, but once again he lost the title to Holly within the space of several hours.[11] Killings became somewhat of a background figure of "The Invasion" angle during the summer months, often seen in dressing rooms and watching television with other superstars during inter-promotional matches. Killings was released from the WWF the next year.[8]

Killings signed with the Nashville, Tennessee-based Total Nonstop Action Wrestling promotion in June 2002, and appeared on the first weekly TNA pay-per-view on June 19 as K-Krush. Killings immediately established himself as a heel by harassing NASCARdriversSterling Marlin and Hermie Sadler until he was attacked by Brian Lawler. Later that same evening, he participated in the Gauntlet for the Gold match, but was eliminated by Malice. The following week, Killings lost to Christopher after Marlin and Sadler interfered in their match. On July 3, Killings and Jeff Jarrett defeated Christopher and Scott Hall after Christopher turned on Hall during the match, aligning himself with Killings and Jarrett. On July 10, Killings defeated Hermie Sadler in a squash match. The decision, however, was overturned after Killings continued to attack Sadler after he had been awarded the match.

On the July 17 TNA pay-per-view, Killings delivered an angry promo in which he implied that he had been held back as a result of his race. He then stated that he was to be referred to as "The Truth". Killings eventually began using his own name, referring to himself as Ron "The Truth" Killings. Killings defeated Ken Shamrock for the NWA World Heavyweight Championship at NWA-TNA 8 on August 7, thus becoming the first-ever, and to date only, recognized African-American NWA World Heavyweight Champion in history, and the fourth African American in professional wrestling history to win a World Heavyweight title.[8] He successfully defended the title in matches with Monty Brown, Jerry Lynn, Low Ki, Curt Hennig, and Scott Hall before losing on November 20 to Jeff Jarrett who had the help of Vince Russo.[8] As a result of Russo's involvement, Killings turned into a face. In subsequent months, Killings feuded with Sports Entertainment Xtreme before turning into a heel once again by attacking Jarrett on March 19.[8] He later introduced Nelson Knight as his bodyguard.[8]

After several abortive attempts to regain the tag title, the Kru began supporting Killings' bid to become NWA World Heavyweight Champion. On June 9, NWA World Heavyweight Champion Jeff Jarrett took part in a "3Live Kru Challenge" which saw him face Konnan, James and Killings in three subsequent matches. Jarrett defeated Konnan in a strap match and James in a "trailer park trash match" (hardcore match), but lost to Killings in a "Ghetto Justice match". On May 19, Killings faced NWA World Heavyweight Champion A.J. Styles, Raven, and Chris Harris in a four-way title match. He won the bout, becoming a two-time NWA World Heavyweight Champion, after Jarrett hit Styles with a guitar. His reign lasted until June 2, when Jarrett defeated him in a King of the Mountain match which also included Harris, Styles, and Raven. The Kru went on to feud with Jarrett's mercenaries, the Elite Guard (Chad Collyer, Hotstuff Hernandez, and Onyx). On July 14, the 3 Live Kru, Dusty Rhodes, and Larry Zbyszko defeated Jarrett, Ken Shamrock, and the Elite Guard in a ten-man tag team match. The Kru began feuding with Team Canada in August. At Victory Road on November 7, Konnan and James defeated Team Canada members Bobby Roode and Eric Young for the NWA World Tag Team Championship. After Konnan suffered an injury, Killings and James lost the title to Team Canada at Turning Point on December 5.[8] Throughout early-2005, the Kru feuded with Michael Shane and Kazarian, Team Canada, and The Naturals.

Dissension arose after James' former tag team partner from the WWE, Billy Gunn, joined TNA as "The New Age Outlaw" and began trying to convince James to reform their former tag team, the New Age Outlaws. Killings and Konnan feuded with The Outlaw and Monty Brown, with James's loyalties divided. Brown and The Outlaw, who had by now renamed himself "Kip James" as a psychological ploy, defeated Killings and Konnan at No Surrender on July 17, with James declining to help either team. Killings and Konnan became increasingly frustrated, at one point referring to themselves as the "2Live Kru", although Killings repeatedly attempted to act as a mediator between James and Konnan. The two teams faced one another in a No Surrender rematch on August 14 at Sacrifice, with James appointed special guest referee by Director of Authority, Larry Zbyszko. James reaffirmed his loyalty to the Kru by attacking Kip, enabling Konnan to pin him and win the match. The 3Live Kru won a six-man tag team match against The Diamonds in the Rough at Unbreakable on September 11. After Impact! premiered on Spike TV on October 1, Kip James entered the picture once more, but appeared to be helping 3LK this time. He refereed a Hockey Stick Fight at Genesis on November 13, which 3LK won. Kip James later joined the stable, which became known as "4Live Kru". On December 11 at Turning Point, the 4Live Kru faced Team Canada in an eight-man tag match. In the course of the match, Konnan hit Kip and B.G. James with chair shots, enabling Bobby Roode to pin Kip. He then attempted to celebrate with Killings, who appeared shocked by Konnan's actions. Killings later told Konnan he was done with the Kru.

On April 26, R-Truth was drafted to Raw as part of the 2010 WWE draft. He began a feud with Ted DiBiase after DiBiase offered him a job as his personal assistant, which Truth declined with a slap. Two weeks later, during a match with William Regal, Truth was attacked by Carlito and Primo, who were paid off by DiBiase after the assault. Truth went on to wrestle and defeat DiBiase at Over the Limit on May 23.[24] The next night on Raw, Truth defeated The Miz to win the vacant United States Championship, giving him his first singles championship since returning to WWE.[25] On the June 14 episode of Raw, Truth lost the United States Championship to The Miz in a fatal four-way match also featuring John Morrison and Zack Ryder.[26] He invoked his rematch clause at Fatal 4-Way, but was unsuccessful.[27] At SummerSlam, R-Truth was part of Team WWE, defeating The Nexus.[28] On the October 11 episode of Raw, he defeated Ted DiBiase to qualify for Team Raw at Bragging Rights to face Team SmackDown.[29] Team Raw lost the match for the second consecutive time.[30][31] In December, R-Truth mentored Johnny Curtis in the NXT's fourth season. On March 1, 2011, Curtis won the fourth season of NXT.[32] As winners, Truth and Curtis won the right to challenge for the Tag Team Championship.[32]

On the April 11 episode of Raw, Truth became the number one contender for the WWE Championship along with John Cena via double disqualification after The Miz and Alex Riley attacked both of them during a number one contender's gauntlet match.[33] Truth had previously defeated Dolph Ziggler and John Morrison prior to facing Cena at the end of the gauntlet. Raw General Manager stated that, due to interference from Miz and Riley, R-Truth and Cena would both compete for the WWE Championship at Extreme Rules in a steel cage match.[33] On the April 18 episode of Raw, John Morrison questioned Truth about his capability to compete in a match like this, and challenged Truth to a match for his spot. Later that night, after Morrison won the match, Truth brutally attacked Morrison, turning heel in the process.[34][34] The following week on Raw, R-Truth cut a promo, stating that popularity did not get him any titles, and also announced that he was done entertaining the fans.[35] At Extreme Rules on May 1, Truth prevented Morrison from escaping the cage during the main event for the WWE Championship, ultimately costing him the title. On the May 9 episode of Raw, Truth revealed that his attack on Morrison had led to him being hospitalized before then attacking Rey Mysterio at the end of the show.[36] On the May 16 episode of Raw, Truth accused Mysterio of being a "thief" and stealing his chance at the WWE Championship. Truth then attacked a weakened Mysterio, who had just finished a match with Alberto Del Rio.[37] Truth faced Mysterio at Over the Limit, where he was victorious.[38] After subsequent episodes of ranting and raving over John Cena's popularity, he harassed a young fan and his dad on the May 30 episode of Raw, throwing a cup of soda in the dad's face after a countout win over Cena.[39] After Raw went off the air, Raw General Manager announced a WWE Championship match between the two, on the condition that R-Truth apologize for his behavior the next week.[40] On the June 6 episode of Raw, Truth interrupted both "Stone Cold" Steve Austin and Vince McMahon and made his way out to the ring, singing a song about "Little Jimmy" (referring to the children in attendance) and wearing a Confederate soldier's uniform. However, he stayed true to his word and "apologized" for his actions the previous week.[41] As a result, he faced John Cena at Capitol Punishment for the WWE Championship, but was unsuccessful in winning the title.[42]

Awesome Truth in November 2011

On the August 22 episode of Raw, R-Truth and The Miz attacked Santino Marella before his match and then proceeded to cut a promo bashing Triple H about not using them properly. On the August 29 episode of Raw, Truth interfered in The Miz's match and the both of them attacked CM Punk. On the September 5 episode of Raw, Truth and Miz challenged Air Boom (Evan Bourne and Kofi Kingston) to a match for the Tag Team Championship at Night of Champions, but were disqualified after Miz assaulted a referee during the match.[43] R-Truth and Miz were subsequently fired by Triple H the following night on Raw.[44] At Hell in a Cell, R-Truth and Miz interrupted main event and attacked Alberto Del Rio, CM Punk, John Cena and referees after the WWE Championship match ended. After this, the entire WWE roster came out to find a way into the cell before the officials were able to get the door open and arrest them.[45] On the October 10 episode of Raw, R-Truth and The Miz were reinstated by John Laurinaitis. At Vengeance, Awesome Truth defeated CM Punk and Triple H in a tag team match, due to interference from Kevin Nash.[46] Later that same night they assaulted John Cena during his WWE Championship match with Alberto Del Rio.[47] On November 20 at Survivor Series, Awesome Truth were defeated by Cena and The Rock.[48] The following night on Raw, Cena instigated an argument between R-Truth and Miz, which ultimately led to the team's dissolution as Miz attacked R-Truth with a Skull Crushing Finale onto the stage.[49][50] Following the event, WWE announced that they had suspended Killings for 30 days for his first violation of the Wellness Policy.[51]

On the December 26 episode of Raw, R-Truth returned to attack Miz after the latter lost to John Cena via countout, turning face in the process. This was followed by back-and-forth assaults on the two throughout January.[52] R-Truth entered the Royal Rumble Match at entry #3, but was eliminated by The Miz.[53] R-Truth wrestled for the WWE Championship against CM Punk, Chris Jericho, Dolph Ziggler, Kofi Kingston and The Miz at Elimination Chamber.[54] He was eliminated by defending champion CM Punk.[55]

R-Truth then began to contend for the WWE Tag Team Championship with Kofi Kingston and competing against Primo and Epico and Dolph Ziggler and Jack Swagger, which they both won and lost respectively.[56][57] On the February 27 episode of Raw, R-Truth and Kingston failed to capture the WWE Tag Team Championship from Primo and Epico in a Triple Threat Tag Team Match, also involving Ziggler and Swagger.[58] At WrestleMania XXVIII, R-Truth and Kingston were members of Team Teddy to face Team Johnny in a twelve-man tag team match to determine the general manager of both brands, which was eventually won by Team Johnny.[59] On the April 30 episode of Raw, R-Truth and Kofi Kingston defeated Primo and Epico to win the WWE Tag Team Championship.[60] At Over the Limit, R-Truth and Kingston successfully defended the title against Dolph Ziggler and Jack Swagger and then again in a rematch on the May 28 episode of Raw.[61][62] In the pre-show of Money in the Bank, R-Truth and Kingston defeated Hunico and Camacho in a non-title match.[63] The following night on Raw, they successfully defended the Tag Team Championship against The Prime Time Players (Darren Young and Titus O'Neil),[64] and again at SummerSlam.[65] At Night of Champions, R-Truth and Kingston lost the Tag Team Championship to the team of Kane and Daniel Bryan[66] and failed to regain the titles from the new champions the following night on Raw.[67] It was announced after the October 8 episode of Raw that R-Truth and Kingston had mutually decided to part ways as a tag team.[68]

R-Truth began feuding with United States ChampionAntonio Cesaro on the October 29 episode of Raw, after saving former tag partner Kofi Kingston from a post-match assault from Cesaro.[69] The following week, R-Truth teamed with Rey Mysterio and Sin Cara to defeat Cesaro and The Prime Time Players, with R-Truth pinning Cesaro for the win.[70] R-Truth faced Cesaro for the United States Championship on November 18 at Survivor Series, but was unsuccessful in winning the title.[71] On the following episode of SmackDown, R-Truth defeated Cesaro in a non-title match.[72] On the December 3 episode of Raw, R-Truth was again unsuccessful in capturing the United States Championship from Cesaro in fatal-four-way match, also involving Kofi Kingston and Wade Barrett.[73] On December 16 at TLC: Tables, Ladders & Chairs, R-Truth failed again to capture the United States Championship from Cesaro.[74] Following an injury he suffered at TLC, Truth returned on the February 18, 2013 episode of Raw, saving Kofi Kingston from Damien Sandow.[75] At Battleground, R-Truth unsuccessfully challenged Curtis Axel for the Intercontinental Championship.

On the November 18 episode of Raw, R-Truth teamed with Xavier Woods, who he had teamed previously with in TNA, to defeat 3MB (Drew McIntyre and Jinder Mahal), who were for that night called The Rhinestone Cowboys. On the November 29 episode of SmackDown, R-Truth and Woods began a feud with Brodus Clay after Clay took offense to Woods using his entrance music and The Funkadactyls as his managers earlier in the week on Raw.[76] On the December 2 episode of Raw, R-Truth and Woods defeated Tons of Funk (Clay and Tensai) in a rematch after Woods pinned Clay.[77] At TLC: Tables, Ladders & Chairs, R-Truth defeated Clay after Clay was distracted by Tensai leaving after having enough of Clay's behaviour.

At Royal Rumble on January 25, 2015, R-Truth entered the Royal Rumble match at number 2, but was eliminated by Bubba Ray Dudley. At Fastlane, after Dean Ambrose lost by disqualification against Bad News Barrett for the Intercontinental Championship, Ambrose stole the title from Barrett.[78] This led to various wrestlers gaining possession of Barrett's title belt over the next few weeks, including R-Truth, Dolph Ziggler, Daniel Bryan, Luke Harper and Stardust. During this, it was announced on WWE.com that Barrett would defend the title in a multiple-man ladder match at WrestleMania 31, with each wrestler who stole the title from Barrett being announced in the match over the next several weeks.[79][80][81] At the event, R-Truth was unsuccessful in winning the championship.[82] On the April 27 episode of Raw, R-Truth took part in the 2015 King of the Ring tournament, defeating Stardust in the first round. The following night on the WWE Network, R-Truth lost to Bad News Barrett in the semi-finals.[83] R-Truth defeated Stardust at Payback pre-show. R-Truth participated in the Elimination Chamber match for the vacant Intercontinental Championship, but was eliminated by Ryback, who later won the match.

At the Battleground pre-show, R-Truth faced Barrett in a "Battle for the Crown" match, where if Barrett lost, R-Truth would receive Barrett's crown, R-Truth failed to win the match, which ended their feud.

On the January 7, 2016 episode of SmackDown, R-Truth announced that he would be entering the Royal Rumble match. R-Truth was eliminated from the match after bringing a ladder into the ring and climbing it, incorrectly believing the match to be the Money in the Bank ladder match (this was part of a character trend where he was at least one PPV behind on everything.) Upon realizing his error, Truth was eliminated by Kane.

In the following weeks on Raw and SmackDown, Goldust approached R-Truth and proposed they form a tag team to no avail.[84][85] At the Fastlane pay-per-view, Goldust came down to aid R-Truth at ringside in his match against Curtis Axel, inadvertently distracting R-Truth before Axel rolled him up for the win.[86] After multiple attempts from Goldust, ending with R-Truth denying his request, R-Truth began to apologize and attempt to form a tag team with Goldust, with Goldust denying R-Truth.[87][88][89] At WrestleMania 32, R-Truth entered André the Giant Memorial Battle Royal but was eliminated by Adam Rose and Heath Slater. For a number one contender's tag team title tournament, on the April 13 episode of SmackDown, he was scheduled to team with Goldust for the match but was replaced by Fandango due to a refusal to team with R-Truth by Goldust. A week later, R-Truth aligned himself with Tyler Breeze due to Goldust's alliance with Fandango. On the May 2 episode of Raw, Breeze defeated Goldust after interference by R-Truth.[90] A week later on Raw, R-Truth defeated Fandango, with Breeze in R-Truth's corner.[91] On the May 12 episode of SmackDown R-Truth and Breeze faced Goldust and Fandango. During the match, R-Truth and Goldust refused to fight each other. As a result, Breeze and Fandango attacked Goldust as Fandango allowed Breeze to pin Goldust for the win. R-Truth attempted to rescue Goldust from the attack, only to get beaten down by the two along with him.[92] The next week on Raw, R-Truth and Goldust debuted as The Golden Truth against Breezango (Tyler Breeze and Fandango) in a losing effort after Truth unintentionally kicked Goldust.[93] Afterwards, Golden Truth started a losing streak, losing to the likes of Breezango and The Dudley Boyz.[94][95] Golden Truth earned their first victory after defeating Breezango at the Money in the Bank event on June 19.[96] On July 19, as part of the 2016 WWE draft, R-Truth, along with Goldust, was drafted to Raw brand. In November, The Golden Truth were later announced as members of team Raw, but later lost their spots a week later when it was revealed R-Truth had sold their spots on the team to The Shining Stars for tickets to Puerto Rico. On the November 7 episode of Raw, The Shining Stars defeated The Golden Truth to join Team Raw.

On the May 15, 2017 episode of Raw, during a promo, Goldust turned on R-Truth, ending The Golden Truth.[97] On the June 26 episode of Raw, R-Truth and Goldust had a brawl before their match even started.[98] R-Truth was defeated by Goldust in a singles match on the July 10 episode of Raw.[99] On the August 28 episode of Raw, R-Truth competed in an Intercontinental Championship number one contender's Battle Royal, which was won by Jeff Hardy.[100] In October, reports suggested R-Truth suffered an arm injury during a match against Elias at a live event.

On April 17, 2018, R-Truth was moved to SmackDown brand as part of the 2018 Superstar Shake-up.[102] During his first months on the brand, Truth was involved in comedic backstage segments with Tye Dillinger, often regarding Truth misunderstanding things.
